High-speed digitization of historic artifacts

CultLab3D’s 3D scanning conveyor belt allows high-speed digitization of historic artifacts. Benedict. 3D printer and 3D printing news website. Nov 19, 2015.
     Researchers at the Fraunhofer Institute for Computer Graphics Research IGD have developed CultLab3D: a 3D scanning system that can create digital images of 3D objects. The project aim is to provide mass digitization, annotation and storage of historical artifacts for museums and other places of preservation. Quotes and notes from the article:

• "Digital preservation is one of the most important methods of sustaining our cultural history."
• digital preservation makes it possible to created and maintain scans of written texts
• "Digital preservation of texts is one thing, but the preservation of physical artifacts is quite another."
• while there is no real substitute for an authentic historical artifact, something should be done to preserve historical artifacts

This organization believes that the digital preservation of historical artifacts via 3D scanning is undoubtedly a worthwhile endeavor.

Presentation on Evaluating the Creation and Preservation Challenges of Photogrammetry-based 3D Models

Presentation on Evaluating the Creation and Preservation Challenges of Photogrammetry-based 3D Models. Michael J. Bennett. University of Connecticut. May 21, 2015.
    Photogrammetry allows for the creation of 3D objects from 2D photography, which mimics human stereo vision. There are many steps in the process, images, masks, depth maps, models, and textures. The question is, what should be archived for long term digital preservation? When models are output into an open standard, there is data loss, since “native 3D CAD file formats cannot be interpreted accurately in any but the original version of the original software product used to create the model.”

General lessons from archiving CAD files, are that, when possible, the data should be normalized into open standards. But native formats, which are often proprietary, should also be archived. With Photogrammetry Data, the author reviews some of the options and recommendations. There are difficulties with archiving the files, and also organizing the files in a container that are documents the relationships of the files. Digital repositories can play a role in the preservation of the 3D datasets.

Threeding Uses Artec 3D Scanning Technology to Catalog 3D Models for Bulgaria’s National Museum of Military History

Threeding Uses Artec 3D Scanning Technology to Catalog 3D Models for Bulgaria’s National Museum of Military History. Bridget Butler Millsaps. 3D Printer & 3D Printing News. February 20, 2015.
The National Museum of Military History is collaborating on a 3D scanning technology to preserve physical pieces of history by creating 3D digital models. With the scans, the museum can create a virtual museum. It also plans to share the models online and allow the public to use 3D printing images to print replicas of the artifacts.
